Optimization And Implementation Of Qingdao PHS Network

Wireless communication system, after the application of the network, has been badly influenced by a lot of uncontrolled factors, such as consumer increasing, network scale expansion, city infrastructure reconstruction and so forth, which result in the weak electronic wave coverage, low successful calling rate, bad quality of connection as well as unbalanced load of the system. Thus, the old elementary wireless network plan can no longer fit current requirements and shall be updated and optimized as soon as possible.With respect to network optimization, it refers to systemically analyze the systematical data, find out the reasons for bad network quality and thus reasonably adjust the network equipment and system parameter through technical methods, and tomake the network work well to ensure the best useing of network resources.This thesis focuses on systematically analyzing the systematical data of PHS network in Qingdao and finding the most reasonable means to measure its performance and bringing forward the network optimization plan. The author will discuss some questions regarding network and find possible ways to solve them. What is more, the author will compare the data of current network with expected data and discuss how to reach the expected data through the implementation of network optimization plan.This thesis will first brief the basic definition of PHS, and then estimate and evaluate the network to bring forward solution for the main problems. Finally, based on the solution, the thesis will focus on finding possible scheme to optimize the network, and re-evaluating it after optimization and making a sum-up. All the materials and data used in this thesis are from the real network, and thus it has strong practical significance.
